SAVEntry

This repo is forked from https://github.com/lamkeewei/SafeEntryLogger. It already have some great value proposition that I am looking for:

• Mark location as favorite to allow for easy check-in without scanning QR code.
• Checkout without having to scan QR code again.
• Automated tap on "check in" and "check out" buttons to skip redundant user interactions (since v2 of SafeEntry actually remembers your personal info)

This repo extends the app the app by exlpoiting features from the Android OS to further streamline the process between engaging your phone and reaching the "check in confirmed" page. The 2 major time and attention consuming hindrances of this process include:

1. The need for unlocking the phone.
2. Searching for the app among all other apps.

As such, Android OS features such as

• Settings Tile Makes the app easily accessible from anywhere, whether you are at lock screen or other apps.
• Activity.showWhenLocked() for checking in or out without having to unlock the phone
• widget for bringing users straight to checked in state rather than having to open hte app and choosing which location.

SafeEntry vs SAVEntry:

Checking in from lock screen:
SafeEntry
Unlock screen -> Search for scanner -> Open scanner -> point to scan -> press "check in" -> press "check in" again -> done
SAVEntry (widget):
Unlock screen -> Choose location from widget -> tap on the location -> done
SAVEntry (Settings tile):
open status bar -> tap on SAVEntry settings tile -> choose location -> done
SAVEntry (from app):
Unlock screen -> Search for SAVEntry app -> Open app -> choose location -> tap on location -> done

Checking out from lock screen:
SafeEntry:
Unlock screen -> Search for scanner -> Open scanner -> point to scan -> press "check out" -> done
SAVEntry (notification):
tap on SAVEntry notification -> unlock screen -> done
SAVEntry (Settings tile):
open status bar -> tap on SAVEntry settings tile -> done
SAVEntry (from app):
Unlock screen -> Search for SAVEntry app -> Open app -> press "check out" -> done

NOTE: Unlocking screen is a step with greatly varying degree of resistance depending on users' configuration.

Generating check-in/out confirmation pages

The app also includes POC for generating check in confirmation page locally is also added.

Motivation of use case is that the main use case of SafeEntry data is to remind users of whereabouts. Government is not using the data to contact users who co-existed with confirmed cases in the same place at the same time see ST article. Hence, storing the visit history locally seems to be doing exactly the same as submitting to SafeEntry server.

Anyway, this functionality is being used as 'last resort' during the unavailability of internet access only.

• Add a new Android application into your Firebase project.
• Download and place google-services.json in the app folder.

Privacy Assurance

None of the user's personal info (NRIC and phone number) is upl oaded or stored in the cloud. The whereabouts of user at any given time is also not recorded on servers. All data are saved locally and users have full control over them. The handling of NRIC and phone number is through the webview, which is exactly the same as the default phone browser Chrome. This app is made open-source for open inspection so as to prove and maintain the above assurance.
